And let the record show that I replied to neuro, but it got deleted.  Like that's never happened before, lol!

I have both the 6D as well as the 5D3. I've tried and did not like using the 50L or the 85L II on the 6D except when I was shooting with a tripod and LV. The positioning of the AF points on the 6D is such that lots of focus-recompose is needed and with the 50L and 85L II, it's just asking for trouble.

While it is true you are more limited with your AF points on the 6D, keep in mind you can focus and crop instead of recompose.

More importantly, the 6D allows for easy switch to Eg-S focus screen unlike the 5D3 - so IMO 6D actually has a significant advantage for manually focusing the f/1.2 lenses and seeing their true DOF in the viewfinder.  One could argue you are looking for trouble in general if you try to autofocus at f/1.2 all the time no matter what camera you use.


Not saying that 6D is a bad camera, but the whinging that takes place over the AF happens deservedly so.

While I see where you are coming from, I disagree.  The 6D does not deserve the criticism it gets regarding its AF.  Why?  Mostly because most of the same folks who are bashing its AF, spent 5 years thinking their 5D2 was a superb camera at a superb price, and rarely complained, if EVER, about its AF performance.  The 6D proves you can get a better camera overall for $1000 less than the 5D2 sold for over most of its life.  So the 6D definitely does not deserve criticism that is really just nitpicking and kicking the next lower model down from the one you like best.

It's only since Canon decided to gift the 5D3 with the 1DX AF sensor, that you suddenly have people saying the 6D has "terrible" AF performance.  It most definitely is not "terrible".  What it is, is "quite usable".  If the successor to the 6D gets the 1DX AF sensor, and sells for the same or lower price than the current 6D...ONLY THEN can you say the 6D had a "terrible AF sensor" for the money.  Because as of now, it does not.

While your image of the girl looks sharp, all I can say is, her nose occupies the right side of the "center 50%" of the image.  My previous point, had to do with the nasties that come about when you go outside that 50%, with an f/1.2 lens, shot at f/1.2.  I thought the side AF points of the 5D3, were well outside this center 50% image area.  In fact I'm pretty sure they are.  The 6D's side point is almost at this location...but would be closer to her ear ring...hardly a matter of much focus and recompose. 

Are you Dylan?  That quote was from his post.

I thought you were discussing side AF points.  Those eyes look pretty centered in the FOV to me, unless this is heavily cropped...which I doubt.

I have both the 6D as well as the 5D3. I've tried and did not like using the 50L or the 85L II on the 6D except when I was shooting with a tripod and LV. The positioning of the AF points on the 6D is such that lots of focus-recompose is needed and with the 50L and 85L II, it's just asking for trouble.

Strange as it may sound, the 135L doesn't give me nearly half as much trouble - and yes, I AFMA all my lenses using FoCal.

OTOH, I hardly ever face trouble with the outer focus points on the 5D3 - it is pointless comparing the AF systems on both cameras. The 6D isn't built for fast action shooting - you may be able to get some shots in focus, but the chances of an OOF shot are higher.

True enough.  I've not tried either the 50L or 85L on my 6D, yet.  My 135L actually gives more AF trouble than all f/4 aperture zoom lenses I've owned or used on it, which I have stated before.  This is the nature of the 6D AF sensor.  The 85L that I rented 4 years ago, certainly would not AF accurately on my 50D no matter what I did with the AFMA.  When in an earlier post above, I said the 5D3 "didn't fare much better" with its outer AF points, I should have said it another way...certainly the 6D's outer points don't compare, and I didn't mean to imply they did.  I experimented with selecting the outer right side AF point this morning, in servo mode with just my 24-105 at 105mm.  It got about 7 shots out of 10 usably sharp, but only 6 out of 10 were critically sharp (the shutter speed was only 1/320 in Tv mode, though...but the light was less than ideal).  This was on a stationary object backlit in a window sill, as I walked toward it while shooting the camera at 4.5 fps.  If this had been a native f/1.2 lens, I have no idea what the "sharp" focus rate would be, but I suspect 3 to 4 out of 10 at best.  Again though, those are portrait lenses, not sports lenses, so...neither the camera (6D) nor the lens, is designed to work ideally in servo AF mode anyway.  Mating the two together, is not going to be reliable.  Some say it's usable with still portrait shooting, and that is what I would like to see.

I occasionally see raptors flying high, usually too high for photos. I took the kestrel (middle) and buzzard (bottom) last weekend and the marsh harrier (top) last December. They are all 100% crops, with the birds occupying only 400-500x600-700 pixels, which gives an idea of how far away they were. All are hand-held using the 5DIII + f/2.8 300mm II + 2x TC III at f/5.6. 600mm and iso 640. (I saw them while walking around and could not have used a tripod).

The kestrel looks the best of this group of images, in my opinion.  Did you set ISO to 640, or was it in auto ISO?

Anybody struggling with the Rockwell link should watch a Zefrank video or two on YouTube. True Facts About The Armadillo

how did we get here again?

I was thinking the same thing ... maybe people are only reading the words "photography snob" from the title, and they immediately think of Ken ;D

We're all photography snobs, jaded on some level, are we not?

Yes we are, and I think snobbishness exhibits a skewed bell-shaped distribution with knowledge.
If you know very little, you're not a snob.
As you get to know more, but far less than enough, you develop more and more snobbishness.
You think all you know is correct- and everything else is wrong.
However, once you know a lot, you cross the peak of snobbishness, and you go into enlightenment.
And then on it's all downhill in terms of snobbishness.

Along that scale, my knowledge and snobbishness are both early on the upward slope (fortunately only in terms of photography knowledge, not in my chosen profession, but I have spent a much longer time in that).
Still long way to go here though...  :(

Excellent observation, but if it were true, it would mean the most knowledgeable people are not snobs, and they clearly are.

Or possibly none of us know enough to be truly enlightened :)

Personally, I don't think you can connect knowledge and snobbishness. I know several very knowledgeable photographers, some are arrogant snobs and some are humble and helpfull... and some are a mix. I also know some very poor photographers who have an inflated opinion of themselves.

I suppose you are right, but it does seem like the more knowledgeable posters in this forum, have a bit of snobbery going on.  Their outlook is fairly rigid. 

I don't know any very poor photographers with inflated self opinions.  In fact I don't know any poor photographers at all.  Many of the decent or very good photographers (or professionals), that I know, or have met...Either have extremely high opinions of their work, or of themselves.  This seems especially true of pro's who give seminars, or photo tours.  They state things matter-of-factly, when it's really just their own way of doing things...not recognizing there are other equally good ways of accomplishing the same task.  (For instance the guy who gave a lecture at a photo club meeting I attended, who said he always shoots with a tripod and a polarizer filter, because "you can't get sharp pictures any other way".  That attitude is a hold over from the film days.)  I admit I've not met dozens of lecturers or photo education professionals yet, but of the ones I've met and known...this seems to be the case.  It's their way, or the highway.

Let's face it.  Anyone who spends time and effort on something (whether they're a pro or not), and is happy with the results, would rarely admit there might be the tiniest thing wrong with their approach (or with some virtue they hold to be true)...or attitude.  And as for photo equipment, it's like every other endeavor, or hobby...or cars, planes, boats, houses.  People like, and defend from criticism, what they own.

I wonder how many professional photographers truly enjoy photography?

I think that there is probably more job satisfaction in photography, on the whole, than other professions, though overall earnings are certainly lower than they were twenty years ago in real terms.

However I think the point behind that question is that there is a monumental difference in capturing a picture for your own pleasure of doing it and creating art, and having to get the right picture that is being demanded, and you are being paid to get the result. The later can be quite stressful compared with the former and does indeed take away much of the photography pleasure.

Until you have the final result and everything is hunky dory. Then that's more enjoyable  ;)

+1, well said!

Thanks to all who post comments.  This thread updates so often that I miss comments posted.  I appreciate those who keep up with this on a regular basis.  Here are a few from a recent trip to Bombay Hook NWR, DE.

Great job!

- The 6D's -3 EV lowlight sensitivity is currently unmatched by any DSLR on the market

If you shoot lowlight, sunsets, night photography or landscape photography the lowlight AF performance on the 6D wins.

As I pointed out a few pages ago in this thread:

How do you define 'low light'?  For example, the difference between shooting at -2 EV and-3 EV could mean 1/15 s, f/2.8, ISO 51200 vs. 102400.  Neither is very usable from an IQ standpoint.  What most people call 'low light' is generally substantially brighter than either spec.

Long exposure night photograpy might benefit from that extra stop of AF capability (but in that situation, you are on a triod and probably using Live View to focus anyway).  Sunsets, landscapes and general shooting have plenty of light relative to the AF sensitivity of even lower end dSLRs. 

I think the -3 EV spec of the 6D is Canon saying 'we did it because we can, and to throw a bone after otherwise limiting AF functionality of this body' - it looks good on paper, but is of little practical benefit in the vast majority of shooting situations.

As I've said many times, due to the low noise of the 6D, the low light sensitivity of the center AF point, can be very useful in the majority of situations where you are shooting wildlife (or people) around, before, or after sunset.  Or else if you are shooting landscape hand-held, with an IS lens, up to an hour after sunset...or during a full moon.  Or if you are shooting inside a club, or outside on a dimly lit city street at night, that -3EV capability is very useful.

ISO 6400 is extremely usable for professional prints via the 6D (with a bit of post processing), and ISO's a bit above that are still useful.

As for bashing the other AF points on the 6D, you need to bash the 5D2's as well, because they were no better.  It might not still be on sale, but plenty of forum readers still own and use the 5D2.

For anyone shooting with strobes, or shooting fast sports action in well lit areas, the 5D3 or 1DX is the camera you need (or perhaps a D800 at low ISO).

If you're shooting portraits with an f/1.4 lens, wide open at f/1.4, and require peripheral AF points to be used (for focusing on eyes, etc.), then yes the 6D will not give consistent results.  But then the 1DX and 5D3 don't fare much better in that situation, which is why serious portrait photogs who shoot this way, either manually focus, or use live view.  Of course most of them are closing that fast lens down quite a bit, in which case there is more wiggle room for AF inaccuracies.

And besides, in that peripheral area of these lenses (other than the Zeiss Otus)...those eyes that you claim are so razor sharp...actually are not, and are suffering from coma and astigmatism.  It's unavoidable...especially with such lenses as the 50L and 85L.
This was fine until you mentioned the 5D3 not being much better than the 6D for f/1.4 portraits using the outer AF points. The 5D3 makes the 6D look broken doing this and it's a shame a 60D or a 7D would also make the 6D look broken.

+1 with RLPhoto, I have no problem with outer AF points on my 5D III. Doesn't matter 85L II or 50L

Photo below was taken with 5D III + 50L, outer AF point @ f1.2. Oops...sorry, that was f1.2 not f1.4 as he mentioned

That's a chair, not someone's eyes.  Post one of those please.

A lot of thing to say...little to show ::)

1st photo SOOC, untouch: 5D III + 85L II, 1/160 @ f1.2, outer AF point, was focus on her left eye
2nd little edit in LR

BTW, I have no problem using AF in -3EV lighting condition, yes, with 5D III. Wanna see sample photos?

I thought you were discussing side AF points.  Those eyes look pretty centered in the FOV to me, unless this is heavily cropped...which I doubt.

The outer points on both the 5DII and 6D are perfectably fine in reasonable light and with contrast in the appropriate orientation. But defending them against the likes of the 1D series and now III version of the 5D is pretty pointless. I'm only really familiar with the 1D IIn, but the way that camera nailed focus anywhere made the 5D seem as if it had come out of the Ark. Unfortunately ( or fortunately depending on my sanity) I appreciate that you get what you pay for, but good for Canon putting the majority of it's flagship system in the 5DIII.

However, from what I read, the D600/610 isn't in the 1D /5DIII class of AF anyway despite having loads of x points etc. Nor are the likes of the top end Rebels.

The 6D is a perfectly fine camera but I doubt it will ever satisfy those who wanted a 5DIII at 6D prices.

I don't know of anyone who wanted a 5D3 at 6D prices.  Rather, I suspect there are plenty who would pay $4500 for a 5D3.  They might get to pay that much for its replacement, time will tell.  The replacement will hopefully be worth the price hike.

As I stated, the majority of situations which people call "low light" really offer plenty of light for the AF systems of even low-end dSLRs.  The extra one stop of sensitivity that the 6D has is an advantage only in very rare situations, so rare that many 6D users probably have not ever experienced them.

Having shot with the 6d and my 70-300L I changed my opinion and would disagree here:

The 6d still af's in dim light @f5.6 aperture just fine w/o af assist, and the exposure was taken care of with some flashes and iso 6400. For the big boys with constant f2.8 zooms pr even faster primes that might not matter that much, but for the cheap rest of us 1 more stop of af capability can come in handy

Nice to see you weigh in here.

Not strictly a landscape, but...

Not bad.  I've done a lot of shots like this.
